<p>The device has a deformable shutter (28) provided with transverse ends (30, 32) moving relative to each other. The shutter is deformed between an opening release position in which the shutter has plane shape and opening closing position in which the shutter is curved shape, and the ends are arranged close to each other. An actuating unit (50) actuates displacement of one of the ends relative to another end to generate a displacement force (F). The unit is arranged such that the force is applied on each displaced end, and the displacement of each end causes deformation of the shutter.</p> |
